A couple weeks ago i received the generator from Banggood. The build process was easy. But i dont get a signal out of the machine.

If i measure with the multimeter on all pin the power is good. On the output pin i only measure the offset voltage. If I change the offset voltage in the generator i measure that difference. So the offset is working.

In this forum tread i read that i have to follow the path DAC output --> R9 --> U3B --> R46 --> U4 pin 3 -->U4 pin 5 --> L3 --> U3A. But i can’t find any signal. I used the DSO138 for finding a signal. (great product).

In the starup fase the screen doesn't show the extra information off the U6 firmware. As you can see in the picture. Can this be part of the problem?

I received in july the FG085. But its not working. I only get a offset as output. But no waveform. I measured on every point i could measure with some help of the schematics. But no wavefront. I used a multimeter and the DSO138. If i change the offset in the software that also chancing at the output.

Please check if R13 opened. R13 is at the side of crystal Y1 (please see assembly drawing http://www.jyetech.com/Products/085/Ass ... k_085G.pdf ). Also please check pin 7 of U6. If this doesn't fix the problem U6 might be bad. In this case please contact JYE Tech for a replacement.

FG085, I have no output. Turns on and off and functions appear OK, but no output.In this forum, I read that I have to follow the path DAC output --> R9 --> U3B --> R46 --> U4 pin 3 -->U4 pin 5 --> L3 --> U3A. But I can’t find any signal.In the startup phase the screen doesn't show the extra information off the U6 firmware. This is what it show (DDS: 08502- )Maybe the firmware is broken. So I tried to install a firmware 113-08502-050.hex, U6 (atmega48P) is not recognise with the programer, but U5 (atmega168P) is recognise.I also have check R13 and pin 7 of U6. I think the U6 is faulty.
